Los Angeles County
Under SGMC Chapter 5.33, when a public tree is removed (lawfully under permit or unlawfully), the Director of Public Works may require replacement with a tree of a size, species and condition determined by the Director. For unauthorized removals, the violator additionally owes the tree's full restitution value plus all labor and materials needed to install the replacement. South Gate does not codify a fixed 'X-for-1' replacement ratio in the Municipal Code; replacement is set case-by-case by the Director, generally aiming to match canopy lost and is informed by the Street Tree Master Plan's species palette.

Santa Monica FAQ
How many trees must I plant as replacement?
Typically 1 to 3 replacement trees per removed tree depending on size. Check Santa Monica tree ordinance for ratios.
Can I pay a fee instead of planting?
Many cities offer a fee-in-lieu option that funds the city tree planting program.
South Gate FAQ
How many trees do I have to plant if one is removed?
South Gate does not codify a fixed ratio. The Director of Public Works sets the replacement requirement case-by-case under SGMC 5.33, considering the canopy lost, species, and site. Expect at minimum 1:1 like-for-kind replacement, with larger or signature trees often requiring upsized 24-inch box stock to approximate lost canopy.
Who chooses the replacement species?
The Director of Public Works selects from the Street Tree Master Plan's approved species palette to maintain block consistency, climate suitability, and infrastructure compatibility. You generally cannot substitute a different species without Public Works approval.
Do I have to water the replacement tree?
Yes — typical permit conditions require the applicant to maintain the replacement through an establishment period (commonly 2–3 years) and replace any failures. State MWELO rules (Title 23 CCR §490+) also require water-efficient drip irrigation for landscapes over 500 sq ft.
